Applications
- TTL level shifting
- CMOS level shifting
- SPI/UART/CAN/etc. level shifting
- I2C / I3C level shifting
Operation
Plug in any USB-C cable capable of supplying 5V with at least 100mA of current capability. (most USB interfaces can provide this with no issue). The blue LED near the USB connector will light up to indicate the board is powered. The possible switch configurations for the various voltages are shown below in Table 1. It is always required that Bank B side of the translator always have its voltage set equal or higher than Bank A side of the translator. Device will not be damaged if set wrong, just will not work properly as a translator.
| Bank B Switch | B >= A | Bank A Switch | ||||||||
| ON | OFF | OFF | OFF | 1.8V | ON | OFF | OFF | OFF | 1.5V | |
| OFF | ON | OFF | OFF | 2.5V | bank B voltage must be equal or higher than bank A voltage | OFF | ON | OFF | OFF | 1.8V |
| OFF | OFF | ON | OFF | 3.3V | OFF | OFF | ON | OFF | 2.5V | |
| OFF | OFF | OFF | ON | 5.0V | OFF | OFF | OFF | ON | 3.3V | |
